6 Claims.

This invention is a device for attachment .to a lawn mower-for thepurpose of guiding long grass towards the blades of the reel of themowerfor the cutting of such grass which would otherwise only be presseddown,- and which now'are generally cutthrough the medium of a scythe orsimilar tool.

The'invention, together with its objects and advantages, will be bestunderstood from a study of. the following description taken inconnection with the accompanying drawings wherein:

Figure 1 is a top plan view illustrating the application of theinvention to the lawn mower. Figure 2 is an end elevational viewthereof. Figure 3 is a transverse sectional view. Figure 4 is afragmentary view partly in section and partly in elevation showing thebracket and gear mechanism.

Figures 5 and 8 are detail sectional views taken substantially on lines55 and 8 8, re-

spectively, of Figure 1.

Figure 6 is a ,detail sectional view showing the means for supportingone end of the shaft 25 of the attachment.

Figure 7 is a perspective view of the clampequipped section or plate ofone of the brackets.

Figure 9 is a detail sectional view taken substantially on line 9 9 ofFigure 3.

Referring to the drawings by reference numerals, it. will be seen thatthe invention comprehends the provision of a pair of suitable bracketsl0 lll, and each bracket comprises an attaching section or plate llprovided with a 35 clamp that includes a fixed clamp member I2 'and aremovable clamp member l3. The clamp members l2 and I3 are adapted toembrace the usual rod ll provided on the lawn mower forwardly of thereel I5 thereof and as clearly 40 shown in Figures 1 and 3. The clampmembers l2 and I3 are secured together through the .medium of a screw Itas shown in Figure 8.

Each clamp also includes a plate-like section I! that is connected withthe section .II for 45 adjustment relative thereto through the medium'ofbolt and nutmeans l8 operating in suitable slots I9 as provided in thesection II.

Each of the plate-like sections ll of the clamp are provided w'tharcuate slots 20 in 50 which operate journal pins 2| that are secured atthe desired adjustment through the'medium of a collar 22 and washers 23and nuts 24 as will be clear from a study of Figure 6. At the inner endthereof each journal pin has a reduced end 65 adapted to be received ina socket in one end 1 transmitted from Kitzmiller, Md. 1934, Serial No.739,027

(ones-294) of a shaft 25 as will also be clear from a study -of Figure 6and as indicated at 26.

Rotatable with the shaft 25 as an axis is an elongated sleeve or hub 21to which isspirally secured a screw member 28, the ends of said memberbeing formed to provide sleeves for accommodating securing bolts 29 asclearly shown in Figure 5, andwhich also secure sleeve 2'! to shaft 25.

The blades or spirals of the member 28 have 10 the edges thereofserrated to provide a continuous series of teeth 26' that, as the member28 revolves, engage the long grass bending the same in the direction ofthe reel I5 so that such long blades of grass may be cut by the reelduring 15 the mowing of the grass.

For driving the member 28 there is provided a shaft 30 that is journaledin suitable bearings 3| provided in the upper corners of the platesections I1. The, ends of the shaft 30 are a equipped with rollers 32that are engaged by the-peripheries of the wheels 33 of the lawn mowerin a manner to transmit movement of the wheels to the shaft 30. At oneend thereof the shaft 30 is equipped with a gear 34 thatis 2 in meshwith a gear 35 provided on one end of the sleeve 21, and through themedium of the gearing 34 and 35 the member 28 is driven directly fromthe shaft 3 From the above it will be apparent that by 30 adjusting theplate sections I! relative to the plate sections H, the member 28 may bepositioned nearer to orfarther away from the reel 15; while through themedium of the slots 20 and the-journal pins 2|, member 28 may be 35placed at the desired elevation relative to the grass.

In operation it will be apparent that as the lawn mower is moved overthe grass, motion is the wheels 33- through the 40 pulleys 22, gearing34 and 35, to the member 28 causing the latter to revolve. As the member28 revolves the teeth thereof engage the high grass, bending and guidingthe grass towards the reel I ,5 to be cut thereby. Thus with thisattachment to the lawn mower, it will not be necessary, either before orafter the mowing of the grass with the lawn mower to go over' the areamowed with a sickle or the like for cutting the tall grass which couldnot be taken care of by the lawn mower.

What is claimed is:

1. In a lawn mower having tread wheels, a reel, and a connecting barforwardly of the reel, spaced brackets secured to the connecting bar,

- cut thereby, a shaft extending between and rotatably supported by saidbrackets, rollers on the ends of the shaft having frictional engagementwith the peripheries of the tread wheels, and gearing connecting saidshaft with said screw member for driving the latter.

2. A lawn mower having in combination a reel and a driven screw membermounted forwardly of and in operative position to the reel of the mower,said screw member having a serrated spiral edge for engaging, andbending and directing tall grass towards the reel of the mower to be cutby said reel, and means for driving said member.

3. For use with a lawn mover including a reel whereby the mower may beutilized for cutting tall grass, an elongated screw member rotatablymounted on the mower in advance of and in operative position to the reelof the mower, said screw member having the convolutions thereof providedwith teeth for engaging and directing the tall grass towards the reel,and motion transmitting means connecting said spiral member with thetread wheels of the mower for revolving said screw member incidental tothe revolving of the reel of the mower.

4. An attachment of the character described comprising a pair of bracketmembers each including a pair of complemental sections, means adjustablyconnecting said sections together, a single screw member rotatablysupported by and extending between corresponding sections of saidbracket members, a shaft rotatably supported by and extending betweenthe said corresponding members of said brackets, motion transmittingmeans connecting said shaft with said screw member, and means on theends of the shaft for driving the latter.

5. An attachment for lawn mowers comprising a pair of brackets includinga fixed section provided with clamps for securing said section to thebrace rod of a lawn mower, each of said brackets also including a secondsection, means adjustably connecting the second section of each bracketwith the first section thereof, a screw member having a serrated edgerotatably supported between the second sections of the bracket forengaging and guiding tall grass towards the reel of the lawn mower, ashaft rotatably supported between the second sections of said brackets,rollers on the ends of said shaft for engaging the peripheries of thetread wheels of the lawn mower, and motion transmitting means connectingsaid shaft with the spiral member for drivingthe latter.

. 6. An attachment for lawn mowers comprising mounting brackets, each ofsaid brackets including a clamp equipped section for attachment to thebrace rod of a lawn mower, a bearing equipped section and meansadjustably connecting the bearing equipped, section with the clampequipped section, each clamp equipped section being also provided withan arcuate bearing slot, journal pins having ends engaging the bearingslots, means on for securing the latter at the desired adjustment, ashaft having pins to rotate about said pins as an axis, and a screwmember mounted on the shaft to rotate therewith and including a singlespiral blade the convolutes of which have serrated edges to provide asinuous series of teeth extending from one end to the other of saidscrew member.
